Thermal imaging Is the science of seeing heat patterns using special electronic cameras Rather than seeing light, these remarkable instruments create pictures of heat. They measure infrared (IR) energy and convert the data to images corresponding to the temperature.

How do we get the picture? Each of the pixels, contain an accurate temperature value. The Imager, through the use of a complex set of algorithms, assign specific colors that correspond exactly with the temperature value found at the specific X Y coordinate. When an image is captured using the Therrmal Imager , all of the background data is also 96 Elements saved along with the picture allowing in-depth analysis using software. 128 Elements Corporate Presentation Company Confidential 4http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm
Thermal imaging is non-contact applies to most types of equipment and conditions is obtained without disturbing production quickly identifies specific locations allows for detection of problems before failure can scan large areas quickly to identify areas of concern Corporate Presentation Company Confidential 5http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm
Are Fluke Thermal Imagers easy to use? Yes. If you take pictures with a point and shoot digital camera, you can easily use a Fluke Thermal Imager. Fluke Thermal Imagers can be set either automatic or manual modes, similar to adjustments you might make on a digital camera. Simply: 1. Point 2. Focus 3. Capture As long as you have focused the Imager correctly you basically cannot make any mistakes as you can change Corporate Presentation afterwards with the software everything Company Confidential 6http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm
Lets put the Fluke Thermal Imagers to work Just a few of the applications Electrical Mechanical / Electromechanical HVAC FACT Fluke Thermal Imaging 7 Corporate Presentation Company Confidential 7http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm
Electrical Commonly inspected Typical reasons for temperature components hotspots or deviations (3 phase) Power distribution Unbalanced loads Fuse boxes Harmonics (3rd harmonic current in Cables & connections Neutral) Relays/Switches Overloaded systems/excessive current Insulators Loose or corroded connections increased Capacitors resistance in the circuit (typically one side Substations of components heats up) Circuit breakers Insulation failure Controllers Component failure Transformers Wiring mistakes Motors Underspecified components (like fuses) Battery banks would heat up on both side of the fuse Corporate Presentation Company Confidential 8http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm
Identify a phase unbalance Note the increase in temperature on this phase Corporate Presentation Company Confidential 9http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm
